New measurement of the super(11)B(p, alpha sub(0)) super(8)Be bare-nucleus S(E) factor via the Trojan horse method
A new measurement of the super(11)B(p, alpha sub(0)) super(8)Be has been performed applying the Trojan horse method (THM) to the super(2)H((ProQuest: Formulae and/or non-USASCII text omitted))n quasi-free reaction induced at a laboratory energy of 27 MeV.

| description | A new measurement of the super(11)B(p, alpha sub(0)) super(8)Be has been performed applying the Trojan horse method (THM) to the super(2)H((ProQuest: Formulae and/or non-USASCII text omitted))n quasi-free reaction induced at a laboratory energy of 27 MeV. The astrophysical S(E) factor has been extracted from ~600 keV down to zero energy by means of an improved data analysis technique and it has been compared with direct data available in the literature. The range investigated here overlaps with the energy region of the light element LiBeB stellar burning and with that of future aneutronic fusion power plants using the super(11)B+p fuel cycle. The new investigation described here confirms the preliminary results obtained in the recent TH works. The origin of the discrepancy between the direct estimate of the super(11)B(p, alpha sub(0)) super(8)Be S(E)-factor at zero energy and that from a previous THM investigation is quantitatively corroborated. The results obtained here support, within the experimental uncertainties, the low-energy S(E)-factor extrapolation and the value of the electron screening potential deduced from direct measurements. |
